| Abstract: | In this paper, a relationship between a dynamic coordinate system and the static reference point was built to realize continuous motion measurement, which was based on the principle of simultaneous localization and mapping (SLAM) and the coordinate transformation method of binocular vision system. We designed a movement course in the experiment to verify the coordinate transformation algorithm, and got a space linear curve based on the world coordinate system. Experimental result shows that after the transformed coordinates, x, y, z three directions of the maximum error is less than 0.734 mm. |
